BUCK ANCHOR.

Application filed April 9,'

This invention relates to building construction and particularly to buck anchors for securing door and window frames to walls formed of tiles or other building units.

Various buck anchors have been used with more or less success in the construction of buildings and many have been unsatisfactory either because the cost of manufacture was excessive or because they could not-be 1o quickly and easily applied to the walls and the buck or because where vertical cables or pipes were disposed in the walls adjacent the doorway it was impossible to apply devices successfully.

It is an object of my invention to provide an exceedingly simple but highly efficient buck anchor adapted to be manufactured at low cost and capable of being quickly and easily installed during the erection of the walls of a building. H

It is a further object to provide a buck anchor readily adjustable to meet various conditions and for use with walls and bucks varying considerably in proportion and especially adapted for use in walls wherein vertical pipes or cables are enclosed within the tiles adjacent the doorway.

These and other objects and advantages of the invention will be apparent from the following description made in connection with the accompanying drawings wherein like reference characters refer to similar parts throughout the several views and in which:

Fig. l is a perspective View showing portions of a fire proof wall formed from unit building material with a doorway formed therein and portions of a door buck mounted in said doorway andanchored to said wall by means of an embodiment of my invention;

Fig. 2 is a cross section through one side of a door buck showing an embodiment of my invention applied;

Fig. 3 is a vertical section taken on the line 33 of Fig. 2; and

Fig. 4 is a vertical section taken on the line H of Fig. 2.

In the drawings, a portion of a wall having a door opening formed therein is shown, said wall being constructed from a multiplicity of hollow building units, such as tiles 5, said units being laid in layers in the usual manner. A door buck of usual construction is shown mounted in the door open- 1928. Serial No. 268,426.

ing, said buck having the vertical legs 6 which may be constructed from two by fours or other suitable material, said legs being securely anchored to the opposing walls of the doorway by means of my improved anchoring device.

As shown, my device comprises a retaining plate 7 which may be of general rectangular shape and if desired corrugated transversely, said plate being adapted to be disposed between two layers of the tiles 5. Plate 7 preferably has a loop at its forward end, as shown, said loop being formed by bending the forward end of the plate inwardly upon itself, as shown in Figs. 2 and 4.

An elongated flexible member, such as a cable or wire 8 passes through the loop 7 of plate 7 its free portions being of substantially equal length and extending horizontally and longitudinally of one of the tiles 5. Adjacent one leg of the buck 6 I mount a spreader member 9, said spreader member having inturned ends forming loops 9 through which the ends of flexible member 8 may pass, spreader member 9 being dispose transversely of the upper edge of the tile 5. -The forward or outer extremities of flexible members 8 preferably straddle the side edges of one of the legs of the buck and are secured to the buck, preferably to the face thereof, by means of nails N or other suitable retaining means, said nails being driven into the buck at acute angles thereto after the extremities of members 8 are secured to the nails, the driving of said nails obviously taking up the slack in flexible members, to hol dthe buck securely against the adjacent edge of the wall defining the doorway. The extremities of flexible members 8 may be secured to the nails in any suitable manner, but I have found that the most convenient way where multistrand flexible members are utilized is to wrap the ends of several strands around the nail in one direction and the ends of other strands around the nail in the opposite direction and then clinch or wind the extremities of the strands together.

In the wall shown, vertical pipes P for gas and electricity are disposed within the tiles in the usual manner known in building construction. The spreader plate 9 may be positioned either just forwardly or rearwardly of the pipes P to hold the ends of flexible I dimensions, since spreader plates 9 of differ ent widths may be used as desired and since the length of flexible members 8 may be varied considerably. Regardless of the number of pipes, cables or other members disposed vertically within the walls of the building adjacentthe door-buck, the anchoring device may be made to function efficiently, since the flexible members which are secured to the door buckmay straddle all pipes 'or other objects disposed within the walls.

From the foregoing description it will be seen that I haveprovided a novel and highly eflicient anchor capable of universal application in walls constructed from building units and adapted to be manufactured at low cost.

Itwill, ofcourse, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing fromthe scope of applicants invention.

l/V'hat is claimed is:

1. A buck anchor comprising a retaining .memberadapted to be secured to a wall adj acent the doorway or the like, within the tile or unit structure of the wall, a flexible member connected to said "retaining member and having ends extending longitudinally of said wall and straddling said buck, spacing .means adjacent said buck through which the ends of said flexible member pass and .means for securing the extremities of said flexible member to .said buck. v

buck anchor comprising a retaining member adapted to be interposed between layers of building units in a wall and spaced a considerable distance from a buck, a flexible member connected with said retaining member and extending therefrom at points spaced widely-apart, the free ends of said flexible member straddling said buck and means disposed at oppositely inclined acute angles to the face of said buck for securing the extremities thereto and for taking up slack in said flexible member.

'3. :A buck anchor comprising a short retaining plate adaptedto be interposed between two layers of building units, and removed at a considerable distance from a buck to be anchored, a flexible member slidably connected with said retaining plate and extending thereform at points spaced widely apart and adjacent the vertical surfaces of a wall formed by said building units, the free ends of said flexible member extending forwardly to straddle said buck, without impedence to vertical elements such as pipes disposed within said wall, and means for securing the extremities of said flexible member to said buck.

41-. A buck anchor comprising a retaining plate adapted to be interposed between two layers of building units and removed at a considerable distance from a' buck to be anchored, a flexible member connected with said retainin member and extendin therefrom at points spaced widely apartand adjacent the vertical surfaces of a wall formed by said building units,'the free ends of said flexible :member extending forwardly, -to straddle said buck without impedence to verical elements, such as pipes disposed within said wall, a spreading or spacing plate dis posedtransversely of said wall adjacent said buck and between layers of said building units and having a pair of spaced eyes disposed slightly outwardly of the vertical surfaces of said wall, the outer ends of said flexible member .slidably engaging said eyes, and means for securing the extremities of said flexible member to said buck.

In testimony whereof I allix my signature.
